Following are the solution to the given question:

Step-by-step explanation:

$H_0:$ Management quality and corporate reputation are independent.

$H_1:$ Management quality and corporate reputation are not independent.

Test statistic:

$\to \chi^2 = \frac{\sum (O-E)^2}{E}$

$= 0.71429 + 0.0102 +2.8809+0.625+1.75 +0.3333 +0+3.2143+7.5\\\\= 17.02806$

The critical $\chi^2$ for $df = (r-1)(c-1) = (3-1)(3-1)= 4$ and $\alpha = 0.05$ is $\chi^2= 9.4877$

Test statistic:

$17.02806 > 9.4877$ therefore rejecting the null hypothesis $H_0$ .

p-value $= 0.001909$

Interpretation:
